If you liked/loved Ozark, Poldark, Little Fires Everywhere, Love (Netflix)

[Silver Gaia]

15. Big Little Lies, Sharp Objects, The Gilded Age

Those three are all HBO shows. The first two I suggested because you liked Little Fires Everywhere, and the third because of Downton Abbey. (The Gilded Age is also from the pen of Julian Fellowes.) Since you liked both Poldark and Downton Abbey, there are a lot of great shows on PBS Masterpiece you might like. For instance, The Durrells in Corfu is a delightful dramedy about a family in the 1930s who move to a Greek island (I secretly want to live there!). That seems to fit some of your genre criteria. There are some period dramas on Starz that you might like, too, like The White Queen or even Outlander. Others here have mentioned Better Call Saul and Fargo. I agree with those choices. Both are outstanding crime dramas with finely drawn and superbly acted characters. We seem to have similar tastes, so if I think of anything else, I will come back to your thread and add it.
